volteer ish: enable lid accelerometer.
Lid accelerometer is BMA253, driver accel_bma2x2.c is used.
Reference to this CL:
https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/1965647
BMA253 uses polling mode since it doesn't have hardware FIFO.
IMU BMI260 will be enabled when driver is available.
b:146144827 is tracking this.
BUG=b:145946347
BRANCH=none
TEST=Verified host iio device has lid accel, can read
name/location/x, y, z raw data, etc.
